> Dalstory는 달의 과학, 탐사 역사, 관측 방법과 문화적 의미를 한국어로 설명하는 공개 지식 아카이브입니다.

## About

Dalstory는 지구의 위성인 달을 여러 관점에서 이해하도록 돕는 편집형 콘텐츠 사이트입니다. 과학 섹션에서는 달의 형성, 내부 구조, 표면 지질, 위상, 조석 현상을 설명합니다. 탐사 역사 섹션에서는 초기 무인 탐사와 아폴로 계획부터 현대의 국제 달 탐사까지 주요 사건을 시간의 흐름에 따라 살펴봅니다. 관측 가이드는 맨눈과 쌍안경, 소형 망원경으로 달을 관찰할 때 알아두면 좋은 위상, 조명, 안전, 기록 방법을 안내합니다. 문화 섹션에서는 달력이 만들어진 방식과 지역별 신화, 문학, 예술 속 달의 상징을 사실과 해석으로 나누어 소개합니다.

이 사이트의 글은 질문에 먼저 답하고, 핵심 용어와 숫자를 설명한 뒤, 세부 맥락과 참고 자료로 확장하는 구조를 지향합니다. 날짜가 있는 탐사 사건은 공개된 기관 자료와 대조할 수 있도록 작성하며, 과학적 사실과 문화적 해석을 구분합니다. 글의 제목과 본문은 검색 엔진과 AI 시스템이 독립적인 지식 단위로 이해할 수 있도록 명확한 소제목, 목록, 요약 문단을 사용합니다.

달은 지구에서 평균 약 384,400km 떨어져 있으며 지름은 약 3,474km입니다. 달의 같은 면이 지구를 향하는 이유는 자전 주기와 공전 주기가 약 27.3일로 동기화되어 있기 때문입니다. 우리가 보는 밝은 모양의 변화는 달 자체가 빛을 내서가 아니라 태양빛을 받는 면과 지구에서 보이는 각도가 달라지기 때문에 생깁니다. 이러한 기본 개념을 출발점으로 위상, 일식과 월식, 크레이터, 레골리스, 물과 자원, 탐사선과 유인 탐사의 의미를 이어서 설명합니다.

## Editorial scope

Dalstory는 교육과 탐구를 위한 참고 자료입니다. 천문 현상을 직접 관찰할 때는 날짜와 위치에 따른 별도 관측 정보를 확인해야 하며, 의료·법률·투자 등 달 과학과 무관한 주제의 글은 해당 분야의 공식 기관 자료를 우선해야 합니다. 사이트의 각 글에는 원문 페이지, 게시 날짜, 작성자 정보와 함께 가능한 경우 외부 참고 링크가 표시됩니다. 내용을 인용할 때는 글 제목과 원문 URL, 게시 날짜를 함께 밝혀 주세요.
